Alternate Radio Connection

The following diagram shows the

DXE-BFS-1

connected

to a radio that does not have a Receive Antenna Input.
This set up allows switching between a transmit antenna
and the beverage antenna using the

DXE-RTR-1A

Receive

Antenna Interface. Refer to the

DXE-RTR-1A

Receive

Antenna Interface manual for more information.
